痕量灌溉管不同埋深对温室茄子生长、产量及水分利用效率的影响

以京茄1号为试材，研究了春季日光温室栽培条件下痕量灌溉管不同埋深对茄子灌溉量、耗水量、产量及品质的影响。结果表明：痕量灌溉管不同埋设深度均能够促进茄子植株生长，提高茄子产量，以痕量灌溉管埋深10 cm处理产量最高，比对照表面覆土处理增产14.7%。随着痕量灌溉管埋深的增加，灌溉量和耗水量降低，但水分生产效率则以埋深10 cm处理最高，达到23.5%。综合考虑各种因素，痕量灌溉管埋深10 cm处理茄子产量最高，耗水量相对较少，水分生产效率最高，是本试验条件下日光温室春茬茄子较适宜的灌溉管埋设深度。

Effects of Different Trace Irrigation Pipe Depths on Eggplant Growth,Yield and Water Utilization Efficiency in Solar Greenhouse

Taking’Jingqie No. 1’as material,the effects of different trace irrigation pipe depths on irrigation quantities,water consumption,yield and fruit quality of spring eggplant(Solanum melongena L.)in solar greenhouse were studied.The results showed that different trace irrigation pipe depths could promote plant growth and increase yield.Compared with the surface casing treatment,when the trace irrigation pipe depth were 10 cm,the yield of eggplant increased by 14.7%.While,with the increasing of trace irrigation pipe depth,the irrigation quantities and water consumption reduced,but the water use efficiency of the trace irrigation pipe depth 10 cm treatment was highest,which reached 23.5%.Considering various factors,among all the trace irrigation pipe depths,the highest eggplant yield and water use efficiency and lower water consumption were appeared in 10 cm depth.Therefore,trace irrigation pipe depth 10 cm was the appropriate trace irrigation pipe depth for spring eggplant production in solar greenhouse.
